This project aims to improve understanding of the process of rapid adaptation. Through both in situ changes and movement of individuals, populations are increasingly encountering new environments, where they risk extinction or become invasive. The fate of populations is determined by how rapidly they adapt to their new environmental conditions. Recent theory predicts adaptation to novel environments is fastest when selection acts on environment-specific genetic variation. This project will test this prediction using novel manipulations. Better understanding of adaptation will allow better prediction of the risks of both extinction and invasiveness of natural populations.

该项目旨在提高对快速适应过程的理解。通过原地的变化和个体的迁移，种群越来越多地遇到新的环境，在那里它们面临灭绝或入侵的风险。人口的命运取决于他们适应新环境条件的速度。最近的理论预测，当选择作用于环境特异性遗传变异时，对新环境的适应最快。这个项目将使用新的操作来测试这个预测。更好地理解适应将有助于更好地预测自然种群灭绝和入侵的风险。
